The News: Coherent announced PhotonLink, an integrated optics platform that combines the company’s photonics component portfolio with precision assembly and test to deliver complete optical solutions for AI datacenters. The platform supports co-packaged optics (CPO), near-packaged optics (NPO), and emerging chip-to-chip connectivity across four functions of the optical path: Generate, Shape, Guide, and Receive. Coherent reported more than 10 CPO customer engagements, more than 10 NPO engagements, and more than 5 chip-to-chip engagements, with anchor customers and long-term agreements secured for both CPO and NPO architectures. PhotonLink revenue is expected to begin ramping in Q4 of CY2026.
“The next leap in AI requires more than faster chips – it requires a new way to connect them,” said Jim Anderson, Chief Executive Officer at Coherent. The launch event on September 21 anchored a broad Coherent presence at the European Conference on Optical Communication (ECOC) 2026 in Málaga, Spain, where the company is also demonstrating a 3.2T pluggable transceiver in an OSFP-size package, a 6.4T NPO optical engine, high-density 2D VCSEL arrays, and a full C-band pluggable optical line system.
Coherent PhotonLink Raises Its TAM to $90 Billion. Will Bundling Win CPO?
Analyst Take: The Coherent PhotonLink launch converts a components catalog into a platform sale. Anderson told the ECOC audience that PhotonLink adds roughly $30 billion of integrated optics opportunity to the company’s 2030 addressable market, raising the total from $60 billion for the existing portfolio to $90 billion. At OFC in March, Coherent sized integrated optics formats at $15 billion within a $23 billion incremental opportunity, so the integrated optics figure has doubled in 6 months. The vision is broad, and it is starting to come into focus. Customer counts, anchor agreements, per-chip content economics, and quarter-specific production timing replaced the conceptual framing of 6 months ago. The company disclosed 2 long-term agreements with leading hyperscale AI datacenter customers for its ultra-high-power laser platform, spanning both CPO and NPO, and put its content opportunity at up to $15,000 per 100 Tbps switch or compute chip on 200G optical lanes when it supplies the complete solution. These TAM and content figures remain vendor-supplied estimates that procurement behavior has yet to validate. The anchor agreements are the first evidence that it will.
Bundling May Overcome Competitive Challenges at Any Single Link
The strategic logic is that bundling may overcome competitive challenges at any single link of the optical chain. Coherent faces credible specialists everywhere: in lasers, in fiber, in silicon photonics, in assembly. Its answer is that no one of them spans the whole path from photon generation to detection, and that integration complexity is precisely what customers asked Coherent to absorb. Anderson said customers requested complete optical assemblies rather than components because stitching together laser sources, isolators, specialty fiber, coupling optics, and detectors from multiple suppliers slows qualification. The implication is that PhotonLink competes on integration and scale rather than on any individual device winning a benchmark, which changes the question buyers must answer from “who has the best laser” to “who can deliver a qualified assembly in volume.”
PhotonLink Bundles the Optical Chain That Customers Struggle to Integrate
The platform’s substance sits in the ingredient technologies and the manufacturing base behind them. On the Generate side, Coherent presented 4 laser platforms: ultra-high-power CW laser arrays for external laser sources, with up to 8 lasers per ELS module; high-power CW lasers for laser-in-package NPO, already shipping millions of units per month into pluggable transceivers; conventional VCSEL arrays production-ready in 1H CY2027; and high-density 2D VCSEL arrays that couple 37 emitters into a single multi-core fiber, production-ready in 2H CY2027. CTO Julie Sheridan Eng walked the photon through the rest of the chain: glass-molded coupling lenses, garnet-based isolators grown from boule in the United States, polarization-maintaining fiber, a mode-matched fiber introduced at ECOC for edge-coupled silicon photonics, microlens arrays, fiber attach units with a new detachable FlexConnect connector, circulators that halve fiber counts, and silicon photonics that demonstrated an industry-first 400G-per-lane link at OFC 2026.
The scale claims are specific. More than 300 million InP lasers shipped, more than 1 billion photodetectors, more than 650 million optical components, and more than 250 million lenses. Capacity is expanding to match, with GaAs lines supporting more than 1 billion VCSEL arrays per year. InP capacity doubled last year, a quarter ahead of schedule, and a further doubling is planned through CY2027 on the industry’s first 6-inch InP production ramp. Production timing frames the revenue story with scale-out CPO ramping in the December quarter, scale-up CPO and NPO following in 2H CY2027, and chip-to-chip landing in the 2029-2030 window. Coherent’s founding role in the OpenCPX MSA adds a standards hedge, keeping its optical engines socket-compatible across vendors as architectures shift.
The December Quarter Ramp Tests Whether Engagements Convert to Revenue
Coherent enters the ramp with financial momentum. The company closed FY2026 with $7.12 billion in revenue, up 22.5% year over year, and its Datacenter & Communications segment grew 58.6% year over year in Q4 to $1.62 billion, 79% of total revenue. Management guided Q1 FY2027 revenue to $2.2 billion to $2.4 billion and confirmed on the August earnings call that CPO revenue begins in the December quarter, the same timing Anderson repeated at the launch. Futurum’s March analysis of Coherent’s OFC briefing noted that NVIDIA’s $2 billion investment will fund the InP capacity expansion now feeding the PhotonLink ramp, with 1.6T optical module demand projected to grow from 1.8 million units in 2025 to more than 30 million units in 2026. The engagement counts disclosed at the launch, 10+ in CPO, 10+ in NPO, and 5+ in chip-to-chip, describe a funnel rather than a backlog, and engagements are not revenue. The 2 long-term agreements and the anchor customers for both architectures are the bankable portion. The chip-to-chip engagements position Coherent in the optical I/O market that Ayar Labs, Lightmatter, and Marvell have pursued with co-packaged optical chiplets, and they extend the platform’s relevance past the switch-centric CPO cycle into the XPU-centric one that follows in 2029-2030.
Every Link of the Chain Faces a Stronger Specialist Somewhere
The competitive field explains why Coherent chose to sell the chain rather than its links. At the system level, NVIDIA’s Quantum-X and Spectrum-X photonics switches and Broadcom’s Tomahawk 6 Davisson, the first 102.4 Tbps Ethernet switch with co-packaged optics, define the CPO sockets that component suppliers feed; both companies design the optical engine themselves and source lasers, fiber assemblies, and detachable connectivity from the merchant market. That structure makes Coherent a content supplier into rival platforms as much as a platform vendor in its own right. Lumentum competes for the same external laser source sockets and has its own NVIDIA relationship. TSMC’s COUPE process pulls silicon photonics integration toward the foundry, and Marvell is building CPO capability into custom XPU programs. In fiber, Corning dwarfs Coherent in volume, though Coherent competes only in specialty fiber, where polarization-maintaining and multi-core designs command premiums. Fabrinet offers hyperscalers a contract-manufacturing path to assemble best-of-breed components without paying for a bundle.
The bear case is that hyperscalers historically prefer to disaggregate suppliers precisely to avoid single-vendor dependence, and the buyers with the most volume, NVIDIA and Broadcom among them, are the least likely to cede assembly value. The bull case is that the 20+ customers now designing CPO and NPO systems without NVIDIA’s or Broadcom’s internal optics teams need exactly what PhotonLink offers, and Coherent’s portfolio-versus-vendors comparison at the launch made the point that laser vendors, fiber vendors, and optics vendors each cover fragments of a chain; only Coherent covers end to end. Speed of qualification will decide which case prevails, and the December quarter ramp gives Coherent the first production data point.
What to Watch
- Whether scale-out CPO revenue appears in Coherent’s December-quarter results as guided
- Whether the 2 ultra-high-power laser long-term agreements are followed by additional named hyperscale commitments
- Whether NPO architectures gain share against CPO as the 2H CY2027 ramps approach
- Whether chip-to-chip engagements convert to design wins against optical I/O specialists such as Ayar Labs and Marvell
- Whether Broadcom and NVIDIA expand merchant sourcing of ELS and fiber assemblies or pull more optical content in-house
